Um, probably none. I'd like to give Corvettes away, or just have one, but since I can't afford to do either of those things, and nobody is likely to give me one or donate theirs to the cause, it's a pretty unrealistic idea.
Even sites like Tom's Hardware, Anandtech, RealHardTechX, HardOCP and TechSpot can't afford to do that, even with their manufacturer ties and corporate backing, so I doubt this is something that even the most well intentioned of individuals would ever be able to accomplish. Plus, you have no credibility, so it's further unlikely that anybody would have the necessary trust factor to just GIVE you anything. Good luck though.
